I just cannot get any of my CH34xx Mini Pro's to program any more.
I have to basically re-run the official CH34xx driver every time for some reason. If you ask it to uninstall straight after installing it... it usually says its not there.
The progress bar in my 1.8.7 IDE always goes past its right hand limit and then just sits there... or it fails immediately.
Doing what I usually do - use an UNO to program them with. TX-TX, RX-RX, 5V to 5V and ground to ground.
Reset to reset doesn't seem to work, not does playing around with the DTR pin on the Mini pro.
Tried different Mini pros... they don't connect either.
Yet, I can appear to write the code to the UNO.
